Can hair be transplanted in between natural hair to increase density? (photos)

It very difficult to evaluate your hair loss case with the photos. It is normal to loose100-150 hairs everyday. Yes, it is possible to increase density with hair transplant surgery BUT first of all,  I will suggest you to book a consultation for evaluation and diagnostic with a local hair loss specialist. Good luck.

To answer your question, yes it can be done. I would suggest that you seek an in person assessment from a specialist and see if this is the best option for you. 

Hair grafts can be placed between normal hairs; however, if these hairs are miniaturized, then there is a risk of hair loss associated with the miniaturized hairs.
